Since they removed the dislike count, I've watched zero technical/programming and related videos on youtube. I'm not going to sit for 30 minutes and then realise the video is a pile of garbage.
I'm amazed that anyone can find any decent programming content on YouTube. There are low-quality beginners webdev tutorials as far as the eye can see, but otherwise there's seemingly very little outside of rambling and superficial conference talks. And on the odd occasion when I do watch a video, YouTube decides that I must be a beginning webdev and bombards me with the aforementioned low-quality Javascript and HTML tutorials for the next several weeks.
